Biotechnology explained in detail: a guide, for beginners

Introduction to Biotechnology

I think biotechnology is a part of science. Biotechnology uses living things, cells and biological systems to make products and tools that help people. Biotechnology mixes biology and technology to fix problems, in the health care field the farming sector, the environment, the industry and food making.

Biotechnology is part of the life. Biotechnology helps make the vaccines and the antibiotics. Biotechnology also helps make the modified crops and the biofuels. Biotechnology is important, in the life.

What Is Biotechnology?

Biotechnology uses what we know about biology and the tools we have to change the living things or the parts of them. Biotechnology creates products or processes that help the society.

In simple words:

👉 Biotechnology means using biology to improve the technology. Biotechnology also helps improve the life.

History and Evolution of Biotechnology

I have learned that Biotechnology is not new; Biotechnology has been around, for thousands of years.

Traditional Biotechnology

Fermentation of bread, wine, and yogurt

Selective breeding of plants and animals

Modern Biotechnology

Genetic engineering

DNA technology

Cloning

Recombinant DNA technology

When I learned about the discovery of DNA structure, by Watson and Crick I saw how DNA structure changed biotechnology. DNA structure gave scientists ways to work in biotechnology. DNA structure still matters today.
